UNITED STATES CAP FOR TELEGRAPH AND TELEPHONE POLES.

SPECIFICATION forming part of Letters Patent No. 303,261, dated August12, 1884.

Application filed April 8, 1884.

To all whom it may concern.-

Be it known that I, GEORGE .L. BROOlVL HALL, a citizen of the UnitedStates, residing at Paterson, Passaic county, State of New Jersey, haveinvented a new and useful Improvement in Devices for Telegraph andTelephone Poles, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof.

The object of my invention is the production of a device for telegraphand telephone poles, by which the tops of the poles are protected fromthe weather and the insulators and Wires are more securely held inposition 011 the poles, which will be hereinafter fully explained. V

Figure 1 of the drawings shows my invention in elevation. Fig. 2 is aplan of the same. Fig. 3 is a plan of the under side of the same, andFig. 4 is a sectional elevation of the same.

A represents a metal cap for telegraph and telephone poles, which cap isconstructed with a pin, 7), in the center, on its upper outer surface,and raised solid hammer-seats 0 near the outer circumference of thesame. The pin Z) is provided with a screw-thread, a, which thread isadapted to receive and accommodate a corresponding screw-thread formedin the glass insulator that screws on the thread a, to which insulatorthe telegraph and telephone wires are secured.

On the outer edge of the spherical disk of theeap A there is formed adepending flange, f, which flange is provided on its outer circumferencewith holes h and on its inner circumference with inward-projecting lugse, which lugs are directly below or under the seats 0, as shown in Fig.2. The under side of the capdisk is provided with angular pointed pinsor prongs d, which are placed midway between the lugs e, as shown inFig. 3.

Figs. 5, 6, and 7 are modifications of that shown in Figs. 1, 2, 3, and4.

In practice the end of the pole D is sawed off, when a circle is struckfor the points of the prongs d, to secure accuracy in starting theprongs, after which action the points of the pins are placed 011 theline, when the hammer may be applied alternately to the ham- No model.)

mer-seats until the prongs and lugs are driven into the pole D, and thedisk of the cap A brought down on the top of the pole D, after which thescrews or spikes are driven through the holes h into the pole D, theflange f serving the purpose of a band for the top of the pole,preventing the pole from splitting during the operation of driving theprongs d and lugs 6 into the end of the same. When my invention is usedin the modified form, this cap is made pointed and is adapted to lit thetops of the telegraph and telephone poles now in use, as the pointed capconforms to the shape of the pole, as shown in Fig. 5. When starting thepointed cap 011 the pole D, the pointed top of the pole will be asufficient guide to start the prongs, in which case the hammer may beapplied to the top of the pin b until the successive blows of the hammerhave brought the cap down onto the top of the pole D, after which thespikes or screws may be driven through the holes h into the poles D, andthe insulator O screwed on the thread a, as shown in Fig. 5.

My invention may be cast whole or in one piece or casting, and is easilyapplied to the pole D, and when placed on corner-poles, where the strainis very great, the prongs d may be barbed, as at d, Fig. 7. Whennecessary to use guys on corners, the cap A can be put on the pole as astay to hold the guy with and keep the guy from crossing the wires. Thiswould apply in cases where the line was not thoroughly equipped with mypins or caps. By this my invention the tops of the poles are preservedfrom decay and the wires are securely held to the pole, saving therebymuch inconvenience and expense in the way of repairs. I

Figs. 8, 9, 10, and 11 show a metal cap with a hollow tube on the disk,in which to insert a wooden pin to hold the insulator, and Figs. 12, 13,and 14 show a metal cap having a disk with arms or straps formedthereon, which will be left for other applications.

Having described my invention and its use, I claim and desire to secureby Letters Patent The metal cap A, constructed with a pin, 1), having ascrew thread, a, the cap having solid hzunnieii-seats c on its disk, andai'izinge, cured to the pole by lugs e, prongs (I, flange f, on itsouter circumference, with holes and f, and spikesorscrews,andinsnizitorO,scre\ved inwmdprojecting lugs c on its innercircuin- 011 thread a, substantially as set forth. l'erence, the flangeserving as a band, the cap 5 having on its inner disk angular pointedpins 1 \Vitnesses:
